Refresh token not found error

Hi,

This looks to be a great plugin but I am having trouble connecting to the Strava API.

I am running a grafana server locally in a docker container but I am getting the following error:

Refresh token not found, authorize datasource first

I have done the following:

• Install the plugin in the docker container with the following command grafana-cli plugins install grafana-strava-datasource
• Restart the docker container
• Create a directory /var/lib/grafana/strava
• Define an environment variable export GF_STRAVA_DS_DATA_PATH=/var/lib/grafana/strava/
• Add a datasource specifying the Client ID and Client Secret from an app created in my Strava account
• I get the following messages

Do you know how I can solve this issue please?

Hey, I’m still getting errors trying to work with the strava datasource.

When I add it it says everything is fine, but when trying to use it I get: Error status: 401 Unauthorized With the following logs

logger=plugin.grafana-strava-datasource t=2022-09-12T09:49:48.67219754Z level=error msg="Strava API request error" error="Error status: 401 Unauthorized"
logger=context traceID=00000000000000000000000000000000 userId=2 orgId=1 uname=<redacted> t=2022-09-12T09:49:48.673140533Z level=error msg="Request Completed" method=POST path=/api/datasources/5/resources/strava-api status=500 remote_addr=10.1.0.41 time_ms=249 duration=249.390115ms size=76 referer="https://grafana.private/explore?left=%7B%22datasource%22% │

Looking in the logs when adding the data source i get the following:

logger=plugin.grafana-strava-datasource t=2022-09-12T09:46:44.184867085Z level=info msg="Starting background prefetcher"
logger=plugin.grafana-strava-datasource t=2022-09-12T09:46:44.196263286Z level=info msg="Cache has been reset" datasource=Strava

But in the gui it reports as a success:

I’m running on grafana version v9.1.2 (3c13120cde)

I changed a fallback for data directory, now if GF_STRAVA_DS_DATA_PATH is not set, files will be created in default OS cache directory (under strava-datasource subfolder). Hope, I will fix issues when token is writing into the file in the root directory. Changes were made in 22a87da1dd4f8b4a17d865e9dfb5d610e3fef1f0 and 7eaddba777394ecc13142befdc2f8a908736e803.
